摘要:
A pulse modulation type transmitter apparatus and a pulse modulation type receiver apparatus wherein both a fast synchronization establishment and a low power consumption of a synchronizing part can be achieved at the same time and wherein the data transmission/reception can be performed soon after a commencement of communication, and further a fast data transmission and a low power consumption can be achieved. A first template signal (1006), which is generated based on a separately transmitted RF frame synchronization signal (1005), is used to generate a frame synchronization signal (1009), and a second frame synchronization timing adjusting part (150) is used to synchronize the frame synchronization signal (1009) with a received RF data signal (1004). Then, a synchronization detection is performed, whereby a prompt pulse acquisition and a prompt pulse phase acquisition can be achieved. After the establishment of frame synchronization, a template switching part (142) is used to switch from the first template signal (1006) to a second template signal (1007) that has been already synchronized with the first template signal (1006). Then, a synchronization detection is performed, whereby the frame synchronization can be maintained.
